Maximum efficiency MonoCrystalline solar cells. Encapsulated with low reflecting water clear epoxy to protect against physical impact and harsh outdoor environments. Helpful Tips Calculating Watts Power [Watt] = Voltage [Volt] x Current [Ampere] Wiring Multiple Solar Panels Series Wiring If your application needs a higher voltage supply source you can wire multiple solar panels in series. You can wire the positive terminal of solar panel #1 to the load and connecting the negative terminal of solar panel #1 to the positive terminal of solar panel #2. In this wiring the total voltage delivered to the load will be doubled and the rated current supply will remain the same. Parallel Wiring If your application needs more power you can wire multiple solar panels in parallel. By connecting the positive terminal of solar panel #1 to the positive terminal of solar panel #2 and connecting the negative terminal of solar panel #1 to the negative terminal of solar panel #2 the maximum current that can be delivered to the load will be doubled. The rated voltage will remain the same.
